Police in Jaffna had their leave cancelled until further notice due to authorities claiming that a clash could break out around the time of Tamil National Remembrance Day (Maaveerar Naal).
The order was issused by the Northern Province's Senior DIG Roshan Fernando on Wednesday evening, the Daily Mirror reported.
Previous years have seen the large scale deployment of police officers and armed military personnel across the North-East in the run up to Maaveerar Naal.
The deployment is viewed with suscipion by Tamils who feel it is an attempt to intimidate residents and dampen remembrance events.
